Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

We’ve rounded up a collection of QHD and UHD monitors to compare the MPG321UR-QD’s performance. For QHD, we have Samsung’s C32G75T, Corsair’s 32QHD165 and Pixio’s PXC327. UHD screens are the Aorus FI32U and Asus PG32UQX.

All the monitors refresh in the expected time except the Pixio which is a tad slower than 165 Hz Corsair. The MPG321UR-QD is right where it should be at 7ms. Coupled with a spectacular overdrive, it’s one of the smoothest Ultra HD monitors we’ve reviewed. Motion blur is minimal, and you won’t find any improvement from the MPRT backlight strobe feature. As we said initially, speed and resolution are mutually exclusive, at least at this point. The top two QHD screens are visibly smoother.

Input lag scores shuffle the field a bit, but the Samsung is still the quickest 32-inch monitor by far. The MPG321UR-QD is respectably fast with a 30ms total score. Only the most skilled players will need a faster monitor than this. There is nothing to complain about here.

Viewing Angles

The MPG321UR-QD is definitely an IPS screen but its red color shift almost suggests a VA panel. If it had 3,000:1 contrast, it would be, but it does not. Though brightness and detail change little as you move from on axis to 45 degrees, the red tint is unmistakable. The top view is a bit blue with lower brightness and less defined detail. One could share this monitor with another user, but it wouldn’t be an ideal experience. It’s best enjoyed alone.

Screen Uniformity

Our MPG321UR-QD sample showed a slight edge glow at the bottom of the screen. The center zone was also a bit hot. However, these artifacts were hard to spot in actual content and dark gaming environments rendered well. There were no color uniformity issues and brighter field patterns showed no problems either.

    i have a M32U-SA 32in UHD . what are the differences between these two? to me it seems only difference is the HDR 600 and the RGB in the back of the monitor - can anybody see any other differnce? color accuracy is very similar but the MSI optix seems to have a bigger color gamut? is that noticeable? is it worth the $135 premium i paid for the M32U?

    Edge lit.
    Poor contrast ratio.
    Brightness not impressive.
    Poor screen uniformity.

    No way in hades I'd pay $900 for this.

    E-sports gamers won't be bothered with UHD monitors. What they want is high frame rates, couple with high refresh rate. I feel most will get a 1440p monitor for gaming if they want to step up from 1080p. The performance lost at UHD is too great, and especially so for fast pace games.
    And when I see edge LED lit, I am not hopeful of good HDR performance. You get very bright backlight @ 600 nits, but it generally lights up the entire screen. So till mini LED or OLED monitors become more mainstream, I think people buying LED lit monitor should not be looking at HDR as the main reason to buy a monitor.

    From the Article: "modern video cards can easily wring 200 fps or more from FHD and QHD screens. Does that matter? Oh yes, it does. Even casual gamers can easily see that difference. "
    I'd lay money that, in a properly-constructed double-blind test, 95% of gamers, casual, expert, or even professional eSports gamers, could not identify the difference between a 140hz and 200hz frame rate, or even between 140 and 360hz.

    32 inches is too big for a desktop monitor for my taste.

    Following the recent firmware updates. Inclusion of Premium Color mode in the OSD and now using the 8K HDMI 2.1 cable to my 12gb 3080 it is now the perfect monitor. That is all.. I am a critic but any saturation in windows with HDR on, flickers and oddities are gone. Colours are perfect.. my KDR is up with is less than 1ms latency and yep, I am one happy chap.
    Turn off your LEDs and enjoy the perfect black and colours in a dark room. boom

    In my actual experience, couldn't be further from the truth with my Optix MPG321UR QD

    The review of the MPG321UR-Quantom Dot 4k needs to be updated. Since the two latest firmware updates on this monitor our colorimeters show it to be almost half the input lag, the HDR is closer to 650-700, Premium color is perfect - when local dimming is off.
    It is currently the best monitor we have tested in store for gaming. While you need to use the DP 1.4a cable during the firmware updates, use the HDMI 2.1 Port (if you have a HDMI 2.1 card) and enjoy extra color performance, less lag and zero signs of any ghosting.
